VEHICLE-SIGNAL.

Specification of Letters Patent.

Patented June 11, 1918:.

Application filed April 26, 1917. Serial No. 164,805.

To all whom it may concern Be it known that. I, FRANK M. WOOD, a citizen of the United States, residing at Portland, county of Multnomah, State of Oregon, have invented certain new and useturns; that. shall be simple and easy to operate, and shall be cheap to manufacture.

I accomplish the above objects by means of the construction illustrated in the accompa-nying drawing, which therefore becomes a part of this application for Letters Patent, like characters of reference indicating like parts throughout the several views thereof, and in which Figure 1 is a perspective view of my dev1ce.

Fig. 2 i a detailed elevation of the head of my device, parts being removed to best illustrate the construction.

Fig. 3 is a sectional plan upon line 3-4) of Fig. 2. h

Fig. 4 is a detailed plan view of the operating yoke. h

Fig. 5 is an elevation of the operating oke. y As illustrated my device is intended to be clamped upon the side of the dash board of the vehicle by means of a clamp having jaws 6 and 7 and a clamping screw 8.

To carry the visible signal portion of my device outward beyond the dash board to a position from which it may easily be seen from all surrounding points I provide an arm 9, preferably integral with jaw 7, and terminating in an upwardly turned portion or head 1 Threaded into said head 10 I provlde a spindle 11 which forms the pivot about which the signal arms 12 rotate.

Each signal arm is integral w1th a hollow semi-conical shell or hub 13 which suron, and offset from said arm a distance substantially equal to the thickness thereof, so

that when said hubs are placed together to encompass the spindle 11 "with their respective arms 12 in alinement, as shown in Fig.

1, the lugs 15 will register respectively with the arms, and may he bolted thereto by bolts 16, as shown in Fig. 1, said bolts thereby securing the two arms 12 pivptally upon spindle 11.

To rotate the arms upon spindle 11 I provide bosses 17 upon the lower ends of the hubs 13, which bosses cc-act when the arms are in place upon spindle 11 to form an eccentric cam, as shown in Figs. 1 and 3.

To operate the said cam I provide a double armed L-shaped yoke pivotally mounted upon head 10 by means of rod '18 which is journaled in bearings 19 and 20 respectively integral with rod 9 and head 10. I

A handle 21 is formed upon the end of rod 18 whereby t-he'device is manually operated; Y v

.The operating yoke consists of a hub 22 secured upon rod 18; arms 23 extending therefrom upon each side thereof substantially normal to rod 18; forwardly extending arms 24 respectively integral with arms 23. in thesame plane therewith, and normal thereto, said arms 24: receiving therebetween the head 10; upwardly extending curved arms 25 respectively integral with arms 24,

said arms 25 curving upward toward each so other in a plane substantially parallel with said head 10; and a curved yoke 26 uniting the adjacent ends of arms 25, said yoke being disposed in a substantially horizontal plane, and being adapted to encompass and to indicate the intended movement of the vehicle.

To return the arms to their initial position after operation thereof I provide a spring within the hubs 13 mounted upon spindle 11, and secured thereon by passing the respective spring ends 27 therethrough, as shown in Fig. 2.

The spring is wound about the spindle 11 right-handedly from one of said ends, and left-handedly from the other of said ends,

the cent al. portion oi": said spring being bent outwardly from spindle 11 to forir a loop 28 adrpted to encompass one of the screws 16 and lie between one of the arms 12 and bo; res 15, as shown in Fig. 2.

My invention mag be made of any size and constructed of any material deemed convenient and'suitable in a device of this ohara'cter, a1id while I have illustrated and described a form of constrl'iotion and arrangement of parts founddesi'rable in materializing my invention, I wish to include in this application for LettersPatent all mechanical equivalents and substitutes that. may fairly'be considered to come within the means to operate said yoke.

2. In a vehicle signal a pair of rotatably mounted members each consisting of an arm, a hub, and a half cam; -said half cams coacting to form a complete cam when said members are secured in place; a spindle up A which said members are pivotally mounted; a yoke. substantially surrounding said spindle and coacting with said complete cam; and means to operate said yoke. 3; In a vehlcle signal, an arm; spindle naeapai upon said arm; a cam rotatably mounted upon said. spindle; a pivotally mounted yoke adjacent said spindle adapted to coact with and to rotate said cam; a signal arm mount ed upon said cam; and means to operate said yoke.

1. In a vehicle signal, a spindle; a pivot ally mounted yoke surrounding saidspindle and consisting of a hub; oppositely and transversely disposed arms extending from said. l'mb,-l01'1gitudinal members forwardly extending from the extremities of each of said arms, curved arms upwardly extending from the extremities of each of said members, and a horizontally curved member uniting theextremities of said curved arms;

- a cam pivotally mounted upon said spindle and encompassed by said horizontally curved member; a signal arm mounted upon said cam; and means'to rotate said yoke.

5. A. vehicle signal comprising a clamp; an arm; an operating rod rotatably mounted upon said arm substantially parallel therewith; a spindle upon the outer extremity of said arm; a yoke secured upon the outer ex tremity of said rod and encompassing said spindle; a cam rotatably mounted upon said spindle and coacting with said yoke; and a signal arm mounted upon said cam.

In witness whereof I claim the foregoing as my own I hereunto affix my signature in the presence of two subscribing witnesses, at-

Portland, county of Multnomah, State of Oregon, this 13th day of April, 1917.
